How do I write a procedure for checking if an input is negative in assembly masm x86? The input number is read by calling readint and stored in eax. The number must be within range (0-4) inclusively. I’ve already used cmp eax,0 and jle immediately after but my program skips the jle so I don’t think my negative number in eax is stored properly.
